CompTIA CV0-004 Practice Test 39
Question 380
The infrastructure architect at a regional health provider investigates this condition: a workload replicates deletion events immediately into a secondary region and assumes that replica is sufficient for accidental deletion recovery. Which explanation best accounts for it?
- Parallel recovery permits verification while leaving existing systems untouched until acceptance.
- Incremental backups depend on a recoverable base and intervening backup history.
- Backup completion logs do not prove application-consistent recoverability.
- Replication can duplicate errors and deletions, while versioned backups provide historical restore points.
Explanation
Correct Answer
D:The evidence of success is: A deleted test record can be recovered from a prior retained point even after replication.
Incorrect Answers
A:That approach would help when a broken production application needs testing before replacing the current environment with restored data. Check the difference through: Inspect replica timing, backup version retention and deletion-protection settings.
B:The alternative is aimed at a different condition: A database restoration plan cannot recover a complete system because it stores only incremental changes without a valid initial backup. Check the difference through: Inspect replica timing, backup version retention and deletion-protection settings.
C:The proposed measure serves a related cloud task, but the present symptom calls for a more specific response. Replication can duplicate errors and deletions, while versioned backups provide historical restore points. Check the difference through: Inspect replica timing, backup version retention and deletion-protection settings.
Question 381
At a global distribution company, an engineer needs to close a case where a workload replicates deletion events immediately into a secondary region and assumes that replica is sufficient for accidental deletion recovery. What test is most decisive?
- A deleted test record can be recovered from a prior retained point even after replication.
- A clean room restore can decrypt test backups using authorized recovery keys.
- A clean recovery exercise starts the workload with intact transactions inside its RTO/RPO.
- The missing document reappears with correct contents and current unrelated files remain unchanged.
Explanation
Correct Answer
A:A deleted test record can be recovered from a prior retained point even after replication. This proves the service behavior rather than just showing a changed configuration. Replication can duplicate errors and deletions, while versioned backups provide historical restore points.
Incorrect Answers
B:That approach would help when an encrypted offsite backup is intact but cannot be restored because its encryption key was destroyed during primary-site recovery. The required acceptance result is: A deleted test record can be recovered from a prior retained point even after replication.
C:A clean recovery exercise starts the workload with intact transactions inside its RTO/RPO. The relevant cloud response here is: A deleted test record can be recovered from a prior retained point even after replication.
D:The missing document reappears with correct contents and current unrelated files remain unchanged. The relevant cloud response here is: A deleted test record can be recovered from a prior retained point even after replication.
Question 382
At a regional health provider, this issue is reported: a workload replicates deletion events immediately into a secondary region and assumes that replica is sufficient for accidental deletion recovery. What should be examined before applying a fix?
- Inspect available snapshots, target path and newer user changes.
- Inspect replica timing, backup version retention and deletion-protection settings.
- Review network isolation, recovery data age and cutover procedure.
- Review key lifecycle, access separation, escrow and disaster scenarios.
Explanation
Correct Answer
B:Inspect replica timing, backup version retention and deletion-protection settings. This distinguishes the relevant dependency before changing cloud resources. Replication can duplicate errors and deletions, while versioned backups provide historical restore points.
Incorrect Answers
A:That approach would help when a shared file volume contains many teams' data and one analyst accidentally deletes a single document. Inspect replica timing, backup version retention and deletion-protection settings.
C:Review network isolation, recovery data age and cutover procedure. The relevant cloud response here is: Inspect replica timing, backup version retention and deletion-protection settings.
D:Review key lifecycle, access separation, escrow and disaster scenarios. The relevant cloud response here is: Inspect replica timing, backup version retention and deletion-protection settings.
Question 383
At a global distribution company, an operational review finds that an encrypted offsite backup is intact but cannot be restored because its encryption key was destroyed during primary-site recovery. What is the best next step?
- Explain and plan differential backups against the latest full backup.
- Use separately controlled immutable offsite backup copies with isolated recovery credentials.
- Store recovery keys with separate controlled backup and test restoration of key access.
- Combine replication with independent point-in-time backups and retention.
Explanation
Correct Answer
C:Encryption protects backup confidentiality but unavailable keys make otherwise intact backups unusable. The change should be verified, not just applied: A clean room restore can decrypt test backups using authorized recovery keys.
Incorrect Answers
A:That approach would help when a team expects each differential backup to contain only changes since the last differential but sizes keep growing during the week. In this case, encryption protects backup confidentiality but unavailable keys make otherwise intact backups unusable.
B:The alternative is aimed at a different condition: A ransomware incident encrypts both production storage and online backups because they share administrator credentials. Encryption protects backup confidentiality but unavailable keys make otherwise intact backups unusable.
D:Replication can duplicate errors and deletions, while versioned backups provide historical restore points. The relevant cloud response here is: Store recovery keys with separate controlled backup and test restoration of key access.
Question 384
An operator asks why the issue arises: an encrypted offsite backup is intact but cannot be restored because its encryption key was destroyed during primary-site recovery. Which explanation is strongest?
- Granular recovery minimizes collateral changes compared with a full-volume restore.
- Parallel recovery permits verification while leaving existing systems untouched until acceptance.
- Incremental jobs capture changes since the previous backup, reducing routine copy volume but complicating restore chains.
- Encryption protects backup confidentiality but unavailable keys make otherwise intact backups unusable.
Explanation
Correct Answer
D:The evidence of success is: A clean room restore can decrypt test backups using authorized recovery keys.
Incorrect Answers
A:That approach would help when a shared file volume contains many teams' data and one analyst accidentally deletes a single document. Check the difference through: Review key lifecycle, access separation, escrow and disaster scenarios.

Question 387
During an approved service change at a global distribution company, a broken production application needs testing before replacing the current environment with restored data. Which action is the most targeted?
- Use incremental backups after a known-good full backup and verify chain recovery.
- Restore only the required file from an eligible recovery point without rolling back unrelated directories.
- Restore a parallel isolated environment and validate it before traffic cutover.
- Perform timed recovery drills with integrity and business-function checks.
Explanation
Correct Answer
C:Parallel recovery permits verification while leaving existing systems untouched until acceptance. The change should be verified, not just applied: The recovered app passes tests in isolation then receives approved traffic after controlled switch.
Incorrect Answers
A:That approach would help when a nightly backup job is too slow because it copies every unchanged file and the recovery requirement allows a backup chain. In this case, parallel recovery permits verification while leaving existing systems untouched until acceptance.
B:Granular recovery minimizes collateral changes compared with a full-volume restore. The relevant cloud response here is: Restore a parallel isolated environment and validate it before traffic cutover.
D:Backup completion logs do not prove application-consistent recoverability. The relevant cloud response here is: Restore a parallel isolated environment and validate it before traffic cutover.
Question 388
During architecture review, a broken production application needs testing before replacing the current environment with restored data. Which statement best explains why the corrective approach works?
- Backup survivability requires access isolation and deletion resistance, not merely additional copies in the same trust zone.
- Backup completion logs do not prove application-consistent recoverability.
- Differentials typically contain changes since the last full backup, so they may grow until a new full baseline.
- Parallel recovery permits verification while leaving existing systems untouched until acceptance.
Explanation
Correct Answer
D:The evidence of success is: The recovered app passes tests in isolation then receives approved traffic after controlled switch.
Incorrect Answers
A:That approach would help when a ransomware incident encrypts both production storage and online backups because they share administrator credentials. Check the difference through: Review network isolation, recovery data age and cutover procedure.
B:The alternative is aimed at a different condition: Backup jobs report success for months but nobody has verified that an application can actually start after restoration. Parallel recovery permits verification while leaving existing systems untouched until acceptance.
C:The proposed measure serves a related cloud task, but the present symptom calls for a more specific response. Parallel recovery permits verification while leaving existing systems untouched until acceptance. Check the difference through: Review network isolation, recovery data age and cutover procedure.
Question 389
A service owner asks for a measurable acceptance test: a broken production application needs testing before replacing the current environment with restored data. Which result should the team obtain?
- The recovered app passes tests in isolation then receives approved traffic after controlled switch.
- A clean room restore can decrypt test backups using authorized recovery keys.
- A compromised production admin cannot delete protected recovery points and a restore succeeds.
- Restore uses the latest full plus the chosen differential without needing all prior differentials.
Explanation
Correct Answer
A:The recovered app passes tests in isolation then receives approved traffic after controlled switch. This proves the service behavior rather than just showing a changed configuration. Parallel recovery permits verification while leaving existing systems untouched until acceptance.
